"They'll know what to do quickly, because it's pretty simple," he said. "The issue will be, can they do it? There's a lot of skills involved. Kind of getting all the moving pieces together. There is a certain skill level and refinement that it takes to get operating where you want to get operating.

"We're kind of an execution-based offense, not really a trick offense, not really a scheme offense. When you're pretty simplistic, you've got to really be able to execute at a high level. That'll be our challenge this spring, not really to learn what to do -- I hope we learn what to do very quickly -- but to develop the skill level to do it."

Consistency is the key.

"That's what makes our offense work," Dykes said. "The 3-yard completion, if the ball is thrown in the right spot at the right time, it results in a big play. If it's not thrown in the right spot at the right time -- the ball's thrown late or slightly behind him -- then you get a lot of 3-yard completions."

Shortly after March 23, when the Bears end workouts with a spring game, Dykes realizes he may no longer have five quarterbacks on his roster.

"A lot of that depends on who the starter is," he said. "Say Jared Goff wins the job, I would expect a lot of guys to leave. I would hope they wouldn't, but that's typically the way the quarterback position works.

"A lot of it has to do with how those guys fit and how much they like it. I hope they all stay. I don't know how realistic that is."
